VPRINTSCREEN Intrinsic
The first step is to separate the screens in EPOCLIST. VEPOCUSE can be used to do this by
following these steps:
1. :RUN TDP.
Clear workspace.
2. USE VEPOCUSE.
Answer the prompts: filename, number of occurrences, and desired PREFIX. VEPOCUSE
will then split the file into ‘n’ files, all prefixed with the PREFIX entered.
3. Text in your document, and include the appropriate screen file in the appropriate
location.
It is recommended that the screen files are “included” into the file, because EPOCLIST has a
record size of 168 bytes, and most document files are set to 80 bytes.

Limitations
The Intrinsic VPRINTSCREEN
• Procedure calls must be modified in order to call the intrinsic from a language which
does not use a VPLUS language id of 5 in the COMAREA. (COBOL, SPL, FORTRAN/66).
• Uses additional stack resources.
